With the Carat EHM0480406 conical tile milling bit, you enlarge and refine holes in tiles and natural stone with complete control. Whether you need to widen an opening for plumbing pipes or bevel sharp hole edges, the conical profile from 20 to 48 mm lets you adjust cutouts accurately using a single tool. Equipped with an internal M14 thread, it mounts directly onto your angle grinder for dry use. This allows you to shape tough ceramic tiles, porcelain, marble, and granite cleanly without chipping.
